The Preparation and Properties of the Low Melting Point Microencapsulated Paraffin Insulation Mortar

Abstract:

Phase-change thermal storage insulation mortar was prepared by using low melting point paraffin as phase change material (PCM), added with appropriate cementing materials, additives and water in this paper. The construction performance, mechanics and thermal properties of the insulation mortar were tested. The results showed that the compatibility between the microencapsulated paraffin (MCP) and inorganic cementing materials was improved by using the silane coupling agent and binder to modify the surface of the MCP, that the cracking of the mortar was solved by introducing the fibers to improve the toughness in the low melting MCP insulation mortar, that the primary physical properties of phase change mortar accord with the standard of the similar mortar, and that it has a favorable phase-change thermal storage ability and an increasingly wide utilization.
